Reducing Flakiness & Keeping Up-to-Date
What Causes Test Flakiness?
Flaky tests are ones that sometimes pass and sometimes fail without any real code change - usually caused by timing issues, unstable locators, or dependencies between tests that should be independent.
Strategies to Reduce Flakiness
Most flakiness traces back to a small set of root causes, each with a well-established fix that should be applied consistently across a suite.
- Replace fixed sleep() calls with explicit waits tied to real conditions
- Ensure tests don't depend on shared state or execution order
- Re-locate elements after any action that changes the DOM
- Isolate test data so parallel tests don't collide with each other
Keeping Your Suite Up-to-Date
| Area | How to Stay Current |
|---|---|
| Selenium Version | Regularly update to benefit from stability and security fixes |
| Browser Drivers | Let Selenium Manager handle version matching automatically |
| Locators | Review and refresh locators after major UI redesigns |
| Dependencies | Periodically update testing libraries (TestNG, Pytest, etc.) |
Closing Thoughts
A reliable automation suite isn't built once and forgotten - it's maintained continuously, applying everything from this learning path: solid locators, proper waits, clean architecture, and disciplined upkeep, to keep tests trustworthy release after release.
